Description

L'invention propose un agencement pour le montage d'un balai d'essuie-glace de type "flat-blade" sur une extrémité de bras d'entraînement en forme de U inversé.The invention provides an arrangement for mounting a "flat-blade" wiper blade on an inverted U-shaped drive arm end.

L'invention propose plus particulièrement un agencement pour le montage et l'articulation d'un balai d'essuyage d'un panneau vitré à une extrémité libre d'un bras d'entraînement du balai d'essuyage en balayage alterné, qui comporte un support fixé au balai d'essuyage et un connecteur fixé à l'extrémité libre du bras d'entraînement et qui est monté articulé par rapport au support autour d'un axe transversal d'articulation.The invention more particularly proposes an arrangement for mounting and hinging a wiper blade of a glazed panel at a free end of a drive arm of the wiper blade in an alternating sweep, which comprises a support attached to the wiper blade and a connector attached to the free end of the drive arm and which is hinged relative to the support about a transverse axis of articulation.

Selon une conception visant à réaliser des essuie-glace de faible hauteur, la structure articulée du balai d'essuyage qui porte la raclette ou lame d'essuyage est supprimée et ce sont des éléments de renfort structurels qui sont associées à la lame d'essuyage souple pour constituer le balai d'essuyage proprement dit, aussi appelé "flat-blade".According to a design for making wipers of low height, the articulated structure of the wiper blade which carries the squeegee or wiper blade is removed and they are structural reinforcing elements that are associated with the wiper blade flexible to constitute the wiper itself, also called "flat-blade".

Le balai d'essuyage est entraîné en balayage alterné sur la vitre à essuyer par un mécanisme d'entraînement conventionnel qui comporte un bras d'entraînement du balai. Du fait de la forme complexe de la vitre à essuyer, le balai est monté articulé autour d'un axe transversal par rapport au bras d'entraînement, par l'intermédiaire d'un connecteur d'articulation.The wiper blade is swept alternately on the wiping glass by a conventional drive mechanism which includes a wiper drive arm. Due to the complex shape of the window to be wiped, the blade is mounted articulated about a transverse axis relative to the drive arm, via a hinge connector.

L'extrémité libre du bras d'entraînement, qui porte le balai, a globalement la forme d'un tronçon de profilé de section transversale en U inversé ouverte vers le bas, dans laquelle est reçu un connecteur d'articulation du balai par rapport à l'extrémité du bras.The free end of the drive arm, which carries the brush, has generally the shape of a section of inverted U-shaped cross-section section open towards the bottom, in which is received a hinge connector of the brush with respect to the end of the arm.

Le connecteur d'articulation est en outre relié au balai d'essuyage par l'intermédiaire d'un support de montage qui est fixé au balai.The hinge connector is further connected to the wiper blade by means of a mounting bracket which is attached to the wiper blade.

Le document WO-A-03.084789 décrit un tel connecteur qui est reçu à l'intérieur de l'extrémité du bras et dans lequel est monté une partie du support de montage.The document WO-A-03.084789 discloses such a connector which is received within the end of the arm and wherein a portion of the mounting bracket is mounted.

Selon ce document, le support de montage comporte un muret central d'orientation longitudinale verticale et dont chaque face latérale porte une tige transversale qui coopère avec le connecteur pour réaliser l'articulation du balai par rapport à l'extrémité du bras d'entraînement.According to this document, the mounting bracket comprises a central wall vertical longitudinal orientation and each side face carries a transverse rod which cooperates with the connector to achieve the articulation of the blade relative to the end of the drive arm.

Un tel agencement est particulièrement avantageux car son encombrement transversale est relativement limité réduit.Such an arrangement is particularly advantageous because its transverse bulk is relatively small.

Cependant, selon cet agencement, le connecteur comporte des pattes arrière qui sont déformables élastiquement et qui coopèrent avec des échancrures réalisées dans les ailes latérales de l'extrémité du bras pour réaliser le verrouillage du connecteur en position dans l'extrémité du bras.However, according to this arrangement, the connector comprises rear legs which are elastically deformable and which cooperate with notches made in the lateral wings of the end of the arm to achieve the locking of the connector in position in the end of the arm.

Ces pattes arrière sont relativement fragiles et rendent la conception du connecteur particulièrement complexe.These rear legs are relatively fragile and make the design of the connector particularly complex.

L'invention a pour but de proposer un agencement pour le montage d'un balai d'essuyage à l'extrémité du bras d'entraînement, pour lequel les moyens de montage du connecteur avec l'extrémité du bras sont relativement simples.The invention aims to provide an arrangement for mounting a wiper blade at the end of the drive arm, wherein the connector mounting means with the end of the arm are relatively simple.

On a représenté aux figures 1 et 2 un balai d'essuyage 10 destiné à être monté à rotation autour d'un axe A transversal à l'extrémité longitudinale avant libre 12a d'un bras d'essuyage 12 par l'intermédiaire d'un connecteur 14.Representatives Figures 1 and 2 a wiper blade 10 intended to be rotatably mounted about an axis A transverse to the free front longitudinal end 12a of a wiper arm 12 via a connector 14.

Le balai d'essuyage 10 comporte une raclette 16 s'étendant longitudinalement, qui est constituée dans sa partie inférieure d'une lame 18 destinée à frotter contre la vitre à essuyer, et dans sa partie supérieure d'un talon de fixation 20.The wiper blade 10 comprises a squeegee 16 extending longitudinally, which is constituted in its lower part by a blade 18 intended to rub against the window to be wiped, and in its upper part by a fixing heel 20.

Le balai d'essuyage 10 comporte aussi des vertèbres de rigidification 24 qui sont chacune reçues dans une rainure complémentaire réalisée dans un bord latéral du talon 20.The wiper blade 10 also comprises stiffening vertebrae 24 which are each received in a complementary groove formed in a lateral edge of the heel 20.

Les vertèbres 24 sont conçues de manière à assurer une rigidité au balai d'essuyage 10 permettant de répartir l'effort d'appui de la raclette 16 contre la vitre à essuyer sur toute sa longueur.The vertebrae 24 are designed to provide rigidity to the wiper blade 10 to distribute the effort supporting the squeegee 16 against the window to be wiped over its entire length.

Le balai d'essuyage 10 porte un support de montage 26 du balai 10 à l'extrémité 12a du bras sur lequel le connecteur 14 est monté, et qui est agencé longitudinalement globalement au milieu du balai 10, en chevauchant le talon 20 et les vertèbres 24 du balai 10.The wiper blade 10 carries a mounting bracket 26 of the blade 10 at the end 12a of the arm on which the connector 14 is mounted, and which is arranged longitudinally globally in the middle of the blade 10, overlapping the heel 20 and the vertebrae 24 of the broom 10.

L'extrémité 12a du bras 12 consiste globalement en un tronçon de profilé d'orientation principale longitudinale qui est de section transversale verticale en U ouvert vers le bas. L'extrémité 12a du bras 12 comporte ainsi un dos supérieur 28 horizontal et deux joues latérales 30 qui s'étendent verticalement vers le bas depuis les bords latéraux du dos supérieur 28.The end 12a of the arm 12 generally consists of a section of longitudinally oriented main profile which is of U-shaped vertical cross section open downwards. The end 12a of the arm 12 thus has a horizontal upper back 28 and two lateral cheeks 30 which extend vertically downwards from the lateral edges of the upper back 28.

Chaque aile 30 comporte une encoche 32 qui est débouchante au niveau du bord longitudinal inférieur 30i de l'aile 30, formant ainsi une ouverture 34 dans le bord inférieur 30i de l'aile, et l'encoche 32 s'étend vers l'arrière et vers le haut depuis l'ouverture 34.Each wing 30 has a notch 32 which is open at the lower longitudinal edge 30i of the wing 30, thus forming an opening 34 in the lower edge 30i of the wing, and the notch 32 extends rearwardly. and upwards since opening 34.

Le connecteur 14 comporte deux flasques 36 longitudinaux verticaux dont chaque flasque 36 s'appuie transversalement contre une aile 30 en vis-à-vis de l'extrémité 12a du bras 12, et dont chaque flasque 36 porte un élément 38 de liaison du connecteur 14 avec l'extrémité 12a du bras 12 et avec le support 26. Pour cela, chaque élément de liaison 38 est reçu dans une encoche 32.The connector 14 comprises two vertical longitudinal flanges 36, each flange 36 of which is supported transversely against a flange 30 facing the end 12a of the arm 12, and each flange 36 of which carries a connecting element 38 of the connector 14. with the end 12a of the arm 12 and with the support 26. For this, each connecting element 38 is received in a notch 32.

Le support 26 comporte une embase inférieure 40 qui est en appui contre la face supérieure du dos 28 du balai 10 et deux pattes latérales inférieures 42 qui s'étend vers le bas depuis l'embase inférieure 40. Les pattes inférieures 42 sont conformées de manière qu'elles sont réparties transversalement de part et d'autre du dos 28 du balai 10 et de manière à réaliser la fixation du support 26 sur le balai 10.The support 26 has a lower base 40 which bears against the upper face of the back 28 of the blade 10 and two lower lateral tabs 42 which extends downwards from the lower base 40. The lower legs 42 are shaped they are distributed transversely on either side of the back 28 of the blade 10 and so as to fix the support 26 on the blade 10.

Le support 26 comporte aussi deux joues longitudinales verticales 44 qui s'étendent verticalement vers le haut depuis chaque bord longitudinal d'extrémité latérale de l'embase inférieure 40 et une tige transversale 46 coaxiale à l'axe A d'articulation qui relie les faces verticales internes 44i en vis-à-vis des deux joues 44.The support 26 also comprises two vertical longitudinal cheeks 44 which extend vertically upwards since each longitudinal end edge of the lower base 40 and a transverse rod 46 coaxial with the hinge axis A which connects the inner vertical faces 44 i opposite the two flanges 44.

La tige 46 permet de réaliser l'articulation du connecteur 14 par rapport au support 26 autour de l'axe transversal A. Pour cela, comme on peut le voir aux figures 3 et 4, chaque tronçon d'extrémité transversale 46a de la tige 46 est reçu dans un logement transversal complémentaire formé par l'élément de liaison 38 associé.The rod 46 makes it possible to form the articulation of the connector 14 with respect to the support 26 around the transverse axis A. For this, as can be seen at Figures 3 and 4 each transverse end section 46a of the rod 46 is received in a complementary transverse housing formed by the associated connecting element 38.

Conformément à l'invention, et comme on peut le voir aux figures 3 et 4, le connecteur 14 est conformé de manière que chaque élément de liaison 38 fait saillie vers l'intérieur depuis la face verticale interne 36i du flasque 36 associé. De plus, lorsque le connecteur 14 est en position montée sur l'extrémité 12a du bras 12, la face interne 36i de chaque flasque 36 est en appui transversalement contre la face verticale externe 30e en vis-à-vis d'une aile 30 de l'extrémité du bras.In accordance with the invention, and as can be seen in Figures 3 and 4 , the connector 14 is shaped so that each connecting element 38 projects inwards from the internal vertical face 36i of the associated flange 36. In addition, when the connector 14 is in the mounted position on the end 12a of the arm 12, the inner face 36i of each flange 36 is supported transversely against the external vertical face 30e facing a wing 30 of FIG. the end of the arm.

Ainsi, le connecteur 14 est conformé de manière qu'il est monté sur l'extrémité 12a du bras 12 selon un mouvement globalement vertical descendant, comme on l'a représenté à la figure 1 par la flèche F1.Thus, the connector 14 is shaped so that it is mounted on the end 12a of the arm 12 in a generally vertical downward movement, as shown in FIG. figure 1 by the arrow F1.

La section verticale transversale du connecteur 14 est elle aussi en forme de U inversé débouchant vers le bas, et le connecteur comporte un dos supérieur 48 globalement horizontal qui est relié à chaque flasque 36, de manière que les flasques 36 s'étendent verticalement vers le bas depuis les bords latéraux du dos 48. Le dos 48 du connecteur est en outre conformé de manière qu'il est en appui vers le bas contre la face supérieure 28s du dos 28 de l'extrémité 12a du bras 12 lorsque le connecteur 14 est monté sur l'extrémité 12a du bras 12.The transverse vertical section of the connector 14 is also inverted U-shaped opening downwards, and the connector has a generally horizontal upper back 48 which is connected to each flange 36, so that the flanges 36 extend vertically towards the bottom. from the lateral edges of the back 48. The back 48 of the connector is further shaped so that it bears downwards against the upper face 28s of the back 28 of the end 12a of the arm 12 when the connector 14 is mounted on the end 12a of the arm 12.

Puisque les éléments de liaison 38 font saillie vers l'intérieur par rapport aux faces internes 36i des flasques 36, et pour permettre le montage du connecteur 14 sur l'extrémité 12a du bras 12, le connecteur 14 est réalisé de manière que les flasques 36 sont aptes à se déformer élastiquement.Since the connecting elements 38 project inwards with respect to the internal faces 36i of the flanges 36, and to allow the mounting of the connector 14 on the end 12a of the arm 12, the connector 14 is made so that the flanges 36 are able to deform elastically.

Ainsi, lors du montage du connecteur 14 sur l'extrémité 12a du bras 12, les flasques 36 s'écartent l'un de l'autre, de sorte que la distance entre les extrémités transversales internes en vis-à-vis 38i des éléments de liaison 38 est supérieure à la largeur de l'extrémité 12a du bras 12.Thus, during assembly of the connector 14 on the end 12a of the arm 12, the flanges 36 move away from each other, so that the distance between the internal transverse ends vis-à-vis 38i elements link 38 is greater than the width of the end 12a of the arm 12.

Lorsque le connecteur 14 est en position montée sur l'extrémité 12a du bras 12, les éléments de liaison sont situés en face des encoches 32, les flasques 36 sont alors rappelés élastiquement dans leur position d'origine représentée aux figures 3 et 4, et entraînent les éléments de liaison 38 dans les encoches 32.When the connector 14 is in position mounted on the end 12a of the arm 12, the connecting elements are located opposite the notches 32, the flanges 36 are then resiliently returned to their original position shown in FIGS. Figures 3 and 4 , and drive the connecting elements 38 into the notches 32.

Les éléments de liaison 38 sont globalement de forme complémentaire à la forme des encoches 32, de manière à limiter les jeux entre le connecteur 14 et l'extrémité 12a du bras 12, selon les directions longitudinale et verticale. De plus, puisque les faces verticales internes 36i des flasques 36 sont en appui contre les faces verticales externes 30e des joues 30 de l'extrémité 12a du bras 12, les jeux selon la direction transversale sont eux aussi réduits.The connecting elements 38 are generally of complementary shape to the shape of the notches 32, so as to limit the clearances between the connector 14 and the end 12a of the arm 12, in the longitudinal and vertical directions. In addition, since the inner vertical faces 36i of the flanges 36 bear against the outer vertical faces 30e of the cheeks 30 of the end 12a of the arm 12, the clearances in the transverse direction are also reduced.

Enfin, puisque le dos supérieur 48 du connecteur 14 est en appui contre le dos 28 de l'extrémité 12a du bras 12, et puisque les encoches 32 sont débouchantes au niveau du bord inférieur de chaque aile 30 associée, les éléments de liaison ne peuvent pas sortir des encoches 32 en traversant les ouvertures 34, réalisant ainsi le blocage du connecteur 14 en position montée sur l'extrémité 12a du bras 12.Finally, since the upper back 48 of the connector 14 bears against the back 28 of the end 12a of the arm 12, and since the notches 32 are open at the lower edge of each associated wing 30, the connecting elements can not not out of the notches 32 through the openings 34, thereby achieving the locking of the connector 14 in the mounted position on the end 12a of the arm 12.

Postérieurement au montage du connecteur 14 sur l'extrémité 12a du bras 12, l'ensemble ainsi formé par le connecteur 14 et l'extrémité 12a du bras 12 est ensuite monté sur le support de montage 26.After mounting the connector 14 on the end 12a of the arm 12, the assembly thus formed by the connector 14 and the end 12a of the arm 12 is then mounted on the mounting bracket 26.

Le montage de cet ensemble sur le support 26 consiste à monter le connecteur 14 et l'extrémité 12a du bras 12 entre les joues 44 du support 26, et à monter les extrémités transversales de la tige 46 dans les éléments de liaison 38, de manière que la face longitudinale verticale externe 36e de chaque flasque 36 est en appui contre la face verticale interne 44i en vis-à-vis d'une joue 44.The mounting of this assembly on the support 26 consists of mounting the connector 14 and the end 12a of the arm 12 between the cheeks 44 of the support 26, and to mount the transverse ends of the rod 46 in the connecting elements 38, so that the vertical vertical outer face 36e of each flange 36 is in abutment against the inner vertical face 44i vis-à- screw of a cheek 44.

Ainsi, chaque flasque 36 du connecteur est situé transversalement entre une aile 30 de l'extrémité 12a du bras 12 et une joue 44 du support de montage 26. Cela permet d'empêcher que les flasques 36 ne s'écartent l'un de l'autre, empêchant ainsi que les éléments de liaison 38 ne sortent des encoches 32.Thus, each flange 36 of the connector is located transversely between a flange 30 of the end 12a of the arm 12 and a flange 44 of the mounting bracket 26. This makes it possible to prevent the flanges 36 from moving apart from one another. other, thus preventing the connecting elements 38 from coming out of the notches 32.

Chaque tronçon d'extrémité 46a de la tige 46 est monté dans un élément de liaison 38 associé par emboîtement élastique.Each end section 46a of the rod 46 is mounted in a connecting element 38 associated by elastic interlocking.

Pour cela, comme on peut le voir aux figures 3 et 4, chaque élément de liaison 38 comporte un tronçon avant 52 et un tronçon arrière 50 dont chacun est cintré de sorte qu'il est de forme concave ouvert vers l'arrière.For this, as can be seen at Figures 3 and 4 , each connecting element 38 comprises a front section 52 and a rear section 50, each of which is bent so that it is of concave shape open towards the rear.

Les deux tronçons avant 52 et arrière 50 délimitent un logement transversal 58 de forme complémentaire à la tige 46, et qui est débouchant au vers le bas au niveau de l'ouverture 34 par laquelle l'encoche débouche dans le bord inférieur de l'aile 30 associée.The two sections before 52 and 50 rear delimit a transverse housing 58 of complementary shape to the rod 46, and which opens downwardly at the opening 34 through which the notch opens into the lower edge of the wing 30 associated.

Le tronçon avant 52 est en appui longitudinalement vers l'avant contre le bord avant 56 de l'encoche 32, et le tronçon arrière 50 est en appui longitudinalement vers l'arrière contre le bord arrière 54 de l'encoche 32.The front section 52 bears longitudinally forwards against the front edge 56 of the notch 32, and the rear section 50 bears longitudinally rearwardly against the rear edge 54 of the notch 32.

Lors du montage d'une extrémité transversale 46a de la tige 46, le tronçon avant 52 de l'élément de liaison se déforme globalement vers l'arrière, pour avoir une forme globalement rectiligne, afin de permettre le passage de l'extrémité 46a de la tige 46 entre les deux tronçons avant 52 et arrière 50 de l'élément de liaison.When mounting a transverse end 46a of the rod 46, the front section 52 of the connecting element deforms generally towards the rear, to have a generally rectilinear shape, to allow the passage of the end 46a of the rod 46 between the two front sections 52 and 50 rear of the connecting element.

Enfin, lorsque le tronçon d'extrémité transversale 46a de la tige est en position montée dans le logement 58, le tronçon avant 52 se déforme élastiquement pour revenir à sa forme initiale représentée aux figures.Finally, when the transverse end portion 46a of the rod is in the mounted position in the housing 58, the front section 52 deforms elastically to return to its original shape shown in the figures.

De plus, la forme cintrée des deux tronçons 50, 52 permet de réaliser un blocage vertical de l'extrémité 46a de la tige 46 lorsqu'elle est montée dans le logement transversal 58 associé, tout en permettant la rotation de l'extrémité 46a de la tige 46 dans le logement transversal 58.In addition, the curved shape of the two sections 50, 52 makes it possible to vertically block the end 46a of the rod 46 when it is mounted in the associated transverse housing 58, while allowing the end 46a to rotate. the rod 46 in the transverse housing 58.

Enfin, comme on l'a dit plus haut, chaque encoche 32 s'étend vers l'arrière et vers le haut depuis l'ouverture 34 associée. Par conséquent, les deux tronçons 50, 52 de l'élément de liaison 38 sont conformés de manière que l'insertion de l'extrémité 46a de la tige 46 dans le logement 58 s'effectue selon un mouvement vers l'avant et vers le bas de l'ensemble formé par le connecteur 14 et l'extrémité avant 12a du bras 12 par rapport au support de montage 26.Finally, as mentioned above, each notch 32 extends rearwardly and upwardly from the associated opening 34. Therefore, the two sections 50, 52 of the connecting element 38 are shaped so that the insertion of the end 46a of the rod 46 into the housing 58 is effected in a forward and forward movement. bottom of the assembly formed by the connector 14 and the front end 12a of the arm 12 relative to the mounting bracket 26.

Selon le mode de réalisation de l'extrémité 12a du bras 12 représenté aux figures, chaque aile 30 est prolongée vers le bas par une languette inférieure 60 et qui est située longitudinalement sur le bord inférieur 30i de l'aile 30 de manière que son bord transversal arrière 60a prolonge le bord arrière 54 de l'encoche 32 vers le bas.According to the embodiment of the end 12a of the arm 12 shown in the figures, each wing 30 is extended downwards by a lower tongue 60 and which is located longitudinally on the lower edge 30i of the wing 30 so that its edge transverse rear 60a extends the rear edge 54 of the notch 32 downwards.

Selon un autre aspect du support de montage 26 conforme à l'invention, son embase inférieure 40 comporte un orifice 62 qui est agencé au dessous de chaque languette 60 et dans lequel est reçue la languette 60 associée.According to another aspect of the mounting bracket 26 according to the invention, its lower base 40 has an orifice 62 which is arranged below each tongue 60 and in which is received the associated tongue 60.

La dimension longitudinale de l'orifice 62 est déterminée de manière à permettre un déplacement libre de la languette 60 associée dans son volume intérieur, lors du pivotement du balai d'essuyage 10 et du support de montage 26 par rapport au connecteur 14 et à l'extrémité 12a du bras, autour de l'axe transversal A.The longitudinal dimension of the orifice 62 is determined so as to allow free movement of the tongue 60 associated in its internal volume, during the pivoting of the wiper blade 10 and the mounting bracket 26 relative to the connector 14 and to the end 12a of the arm, about the transverse axis A.

Ici, l'embase 40 comporte deux orifices 62 qui sont chacun associés à une languette 60. Cependant, il sera compris que l'invention n'est pas limitée à ce mode de réalisation, et que l'embase 40 peut comporter un orifice unique qui est apte à recevoir les deux languettes 60.Here, the base 40 has two orifices 62 which are each associated with a tongue 60. However, it will be understood that the invention is not limited to this embodiment, and that the base 40 may comprise a single orifice which is adapted to receive the two tongues 60.

Ces orifices 62 permettent de réduire la distance verticale entre le bord inférieur 30i de chaque aile 30 de l'extrémité 12a du bras 12 et la face supérieure horizontale 40s de l'embase 40 du support 26. Par conséquent, les orifices 62 permettent de limiter l'encombrement vertical de l'agencement conforme à l'invention.These orifices 62 make it possible to reduce the vertical distance between the lower edge 30i of each wing 30 of the end 12a of the arm 12 and the horizontal upper face 40s of the base 40 of the support 26. Consequently, the orifices 62 make it possible to limit the vertical dimensions of the arrangement according to the invention.

Selon un autre aspect de l'invention représenté aux figures 1 et 2, chaque flasque 36 du connecteur 14 comporte un évidement 64, ou lamage, qui est réalisé dans la face longitudinale verticale externe 36e du flasque 36, et qui est débouchant au niveau du bord longitudinal inférieur 36b du flasque 36.According to another aspect of the invention shown in Figures 1 and 2 each flange 36 of the connector 14 has a recess 64, or counterbore, which is formed in the outer vertical longitudinal face 36e of the flange 36, and which opens out at the lower longitudinal edge 36b of the flange 36.

Le lamage 64 est formé de manière à recevoir une joue 44 associée du support de montage 26, notamment pour améliorer l'aspect de l'agencement selon l'invention.The counterbore 64 is formed to receive an associated cheek 44 of the mounting bracket 26, in particular to improve the appearance of the arrangement according to the invention.

Le lamage 64 comporte une face de fond 36e qui s'étend dans un plan longitudinal vertical, et un bord interne 66 en forme de "U" inversé ouvert vers le bas.The counterbore 64 has a bottom face 36e which extends in a vertical longitudinal plane, and an inner edge 66 in the shape of an inverted "U" open downwards.

La face de fond 36e du lamage forme la face longitudinale verticale externe du flasque 36 contre laquelle la face verticale interne 44i en vis-à-vis du flasque 44 est en appui transversalement.The bottom face 36e of the counterbore forms the vertical vertical outer face of the flange 36 against which the inner vertical face 44i vis-à-vis the flange 44 is supported transversely.

Le bord interne 66 du lamage 64 est situé en vis-à-vis et à distance du bord externe 44a de la joue associée 44 du support 28. Le jeu ainsi formé entre le bord interne 66 du lamage 64 et le bord externe 44a de la joue 44 associée permet au connecteur de pivoter par rapport au support autour de l'axe transversal A d'articulation.The inner edge 66 of the counterbore 64 is located opposite and at a distance from the outer edge 44a of the associated cheek 44 of the support 28. The clearance thus formed between the inner edge 66 of the countersink 64 and the outer edge 44a of the 44 associated cheek allows the connector to pivot relative to the support around the transverse hinge axis A.

Enfin, lors du montage du connecteur 14 sur le support 26, et pour permettre le mouvement vers l'avant et vers le bas du connecteur 14 par rapport au support de montage 26, le bord interne 66 du lamage 64 comporte un tronçon avant 66a qui est incliné par rapport à la verticale globalement vers l'avant et vers le bas, pour permettre le passage d'une portion avant de la joue 44 associée du support de montage 26.Finally, when mounting the connector 14 on the support 26, and to allow the forward and downward movement of the connector 14 relative to the mounting bracket 26, the inner edge 66 of the counterbore 64 comprises a front section 66a which is inclined relative to the vertical globally forward and at the bottom, to allow the passage of a front portion of the associated cheek 44 of the mounting bracket 26.

L'invention a été décrite en association avec un balai de type "flat-blade" selon un mode de réalisation particulier. Cependant, il sera compris que l'invention n'est pas limitée à ce mode de réalisation, et que l'agencement selon l'invention peut être utilisé pour un autre type de balai d'essuyage "flat-blade", le support de montage comportant alors des moyens associés pour sa fixation sur le balai.The invention has been described in association with a "flat-blade" type broom according to a particular embodiment. However, it will be understood that the invention is not limited to this embodiment, and that the arrangement according to the invention can be used for another type of "flat-blade" wiper blade, the support of assembly then comprising associated means for attachment to the brush.
